The solubility of a gas in water is 0.22 g/L at 20.0 kPa of pressure. What is the solubility when the pressure is increased to 1
Allisa [31]

Answer:

Solubility is 1.265g/L

Explanation:

According to Henry's law which states that the solubility of a gas in liquid is directly proportional to the pressure of the gas above the solution.

Sg1 / P1 = Sg2/ P2,

where Sg is the gas solubility, P is the gas pressure.

Sg1 = 0.22

P1 = 20kPA

P2 = 115kPA

Sg2 =?

Sg2 = Sg1 P2 / P1

Sg2 = 0.22 * 115*10^3 / 20*10^3

Sg2 = 25.3*10^3 / 20*10^3

Sg2 = 1.265g/L

the solubility of the gas in water at the new pressure is 1.265g/L

Reasons why convection is responsible for the uneven heating of the air in the atmosphere
igor_vitrenko [27]
FULL ANSWER<span>As the sun heats Earth, land absorbs solar radiation more readily than water, which allows it to heat at a much faster rate. Heat radiates out from the planet's surface to warm the atmosphere through a process known as convention. Wind is created when the air above landmasses absorbs heat from the surface until it begins to expand and rise, drawing in heavier, cooler air from over the oceans to take its place. This process is reversed at night when air above the land cools more rapidly than air above the planet's oceans.Wind patterns and atmospheric currents are formed on a global scale because air near the planet's equator is heated more rapidly than the air found in polar regions. Global wind patterns include trade winds as well the jet stream, a river of air that forms a boundary between polar air masses and the warmer air found closer to the equator.Hope this helps xox :)</span>
